Description

1 '' · 1

The present invention relates to a process for the erection of industrialized, variable and extensible constructions, by assembling juxtaposed and interchangeable modulated elements, as well as the modular constructions obtained following this process. ^

It is common practice to build constructions with load-bearing facades in a modular frame, made up of a load-bearing framework and filling or finishing elements. The framework can be made of wood, metal or reinforced concrete. If the structure is made of wood, it is quite vulnerable to climatic or atmospheric variations as well as to! aging; moreover, it offers little security in the event of a fire and it hardly allows the superimposition of several levels or the covering of large spaces. If the structure is made of steel or reinforced concrete, the installation generally follows a large module of the posts which prohibits or limits any variability or λ possibility of adaptation; in addition, the large section of the posts prohibits incorporating them into the wall thickness which, while limiting the architectural possibilities, causes the creation of thermal bridges and poses problems of protection against the weather.

The supporting framework is built by joining the necessary number of frames comprising horizontal rails, upper and lower, and vertical posts, soli-25 darisation which can be achieved by various means known per se, for example by means bolts or keys. After the construction of the load-bearing framework, it is necessary to place there opaque or transparent modular panels, fixed or mobile, to carry out the corresponding interior covering and to ensure, in all 3tf as far as possible, a good air tightness and humidity. These operations are complicated and require the use of numerous accessory or intermediate parts such as external window frames, lintels, thresholds, shelves, window returns, window frames, etc., which involves the intervention of many trades and the coordination problems that this implies.

The present invention aims to provide elé-I rnents standardized modules which, combined together, offer rl a very wide range of various possibilities to allow the * ι 2 realization of a wide variety of modular constructions with metal support frame incorporated in the facades, which makes it possible to avoid the various aforementioned drawbacks and to economically obtain a construction the volume and appearance of which can be modified and which offers a total guarantee of solidity, sealing and inalterability.

The present invention therefore relates to a method of erection of industrialized, variable and extensible constructions, comprising a load-bearing framework made of metal profiles 10 to which are fixed interchangeable modular panels, opaque or transparent, fixed or mobile, said method being characterized by the fact that the load-bearing framework is concealed in the thickness of the exterior walls of the construction and by the fact that these exterior walls are constructed using: - modulated, waterproof and opaque exterior panels , fixed directly to the bearing structure by clamping, on seals ensuring a flexible and watertight junction between the panels and the support, by means of adjustable fasteners, 20 - opaque insulating interior panels, placed opposite said exterior panels opaque and also fixed to the framework by tightening, - fixed transparent external panels posed without, chassis by tightening on a flexible joint similar to those x cited above

- movable transparent exterior panels constituted by volumes of tempered glass mounted directly, by known means, on the framework and - interior frames for covering the bay windows which dissolve the load-bearing framework and insulate it thermally , these frames being fixed to the frame ensuring constant pressure on the internal face of the glazing by means of a flexible seal provided over the entire periphery.

This variable and extensible building process on one or more levels therefore uses an assembly - according to a modular grid - of load-bearing facades made in the factory. These buildings are therefore composed of / of load-bearing elements made of metal profiles of stan-ojf dimensions dardisëes and of elements carried also standardized, consti- + * 3 killing the exterior and interior finish, opaque or glazed, fixed or mobile, interdependent and interchangeable and fixed directly to the profiles assembled in the form of juxtaposed and / or superimposed frames. The assembly thus has the appearance of a jux-5 taposition and / or a superposition of frames of identical dimensions supporting the floor (s) and the roof structure and to which the finishing elements are directly fixed.

In the method of erecting constructions 10 which is the subject of the present invention, the mobility of the mobile transparent external panels can be carried out in any known manner. According to a preferred embodiment of the invention, this mobility is achieved by sliding by means of rollers on lower and upper metal profiles, fixed directly to the frame; these profiles can be aluminum rails, for example.

Although the metal sections which constitute the framework may be beams, it is preferred to use; use tubular steel sections, square or rectangular.

In order to avoid the risks of phenomena, of condensation in the walls in contact with the outside, it is. advantageous that the external elements of the walls, that is to say the opaque panels, are ventilated.

The joints ensuring a flexible and waterproof junction between the panels and the support are made of synthetic elastomers treated in order to give them good resistance to weathering and aging. It is advantageous to use elastomer strips having an adequate width and presenting on the face to be turned on the side opposite to the support a series of insulated tabs which flatten when the panels are tightened against the support.

If the solid external panels are provided with facing elements, these are advantageously clamped against an elastomer profile ensuring a flexible and tight connection.

The interior opaque panels can be made of any suitable insulating material known per se; wood, expanded or unexpanded plastic, plasterboard /, etc. In order to obtain exceptional insulating properties, it is possible to use ✓ ✓ 4 in known manner - using polyurethane foam panels at least 4 cm thick.

It is obvious. that the method of the present invention is also applicable in the event that one or other of the various panel members is omitted. Thus, for example, the invention remains applicable in the case where the fixed transparent panels or the transparent panels are eliminated. mobile.

The present invention also covers the metal frame constructions constructed according to method v - described above, in one or other of the alternative embodiments.

The invention having been described in general, we will now give a more detailed description -15 serving as an example but not in any way limiting - with reference to the figure of the accompanying drawing.

Example

First, a load-bearing framework is constructed from tubular steel sections welded together to form a grid capable of supporting the weight of a roof, or of one or more storeys and a roof. This frame consists of a bottom rail (1) and an upper rail (2) made of 80/80 square tubes or: optionally 80/40 rectangular tubes to which are welded. following a modulated grid (1 m 21), the post elements (3) in 25 rectangular tubes of 100/50. whose sheet thickness varies from 3 to 8 ram depending on the overloads (number of floors). The bottom rail (1) is sealed by means of anchors (4) to the beta. foundation tone or is welded on metal posts resting on foundation waves.

The ends of the tubular sections are closed off with a welded flat iron to prevent any entry of air and to protect against corrosion. This flat iron protrudes by 2 to 3 mm from the front face of each post in order to serve as a stop for the special EPT joint (ethylene-propylene terpolymer) (5) which 25. will cover the narrow outer face by gluing, over the whole tube height. This joint must be able to withstand large variations in temperature and allow the tightening of the opaque or transparent elements, which close the facades, against the supporting tubular profile; this joint therefore ensures, by its particular design 5 (protruding tabs which flatten during tightening), good water and air tightness over the entire height of the panels as well as the free expansion of all the constituent elements construction.

5 Front panels, opaque (6) or glazed (7), are suspended from the frame by means of "adjustable brackets (8) made of steel or galvanized steel bolted to the top and bottom rails and are tightened against the joints in EPT The setting allows the correct leveling of each panel.

10 The opaque parts are completed, on the interior side, by * a plaster panel (9) lined with polyurethane thermal insulation.

For the glazed parts, a frame (10) of wood, of mass-dyed PVC or of anodized aluminum is slid between the uprights of the frame to which it is fixed and is clamped by simple pressure against the glazing by the interposition a flexible joint also in EPT. This., Frame covers the bay, ensures a double seal and protects the frame while thermally insulating it, which cancels any possibility of thermal bridge. ; j l "
